There is concern that ricin might be used as a potential terrorist weapon. a. true b. false

b. False

Explanation:

Ricin is a poison that is made from the waste left over from processing castor beans. It is a poison that can kill if enough is inhaled, ingested or injected. This leads to the classificationI as a Category B bioterrorism agent (it could threaten water and food safety) So  it can potentially be used as a biological weapon becuase it can be turned into an aerosol and be inhaled.

Despite this, ricin is not generally used as a terrorist weapon. It does not spread from person to person. What could make ricin potentially attractive to terrorists is its availability. But most experts believe that ricin would be difficult to use as a weapon of mass destruction.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
